Mixed-effects models are useful when dealing with data that have both fixed and random effects. We’ll use the lme4 package for this. Step 1: Install and Load lme4 Step 2: Create a Sample Dataset Step 3: Fit a Mixed-Effects Model

Network analysis is essential for understanding relationships in data. We’ll use the igraph package. Step 1: Install and Load igraph Step 2: Create a Sample Graph Step 3: Analyze the Graph

Text analysis is vital for extracting insights from unstructured data. Here, we’ll analyze a simple text corpus. Step 1: Install and Load Required Packages Step 2: Create a Sample Text Corpus Step 3: Create a Term-Document Matrix Step 4: Generate a Word Cloud

Clustering is a powerful technique for grouping similar data points. We’ll use the k-means algorithm. Step 1: Create a Sample Dataset Step 2: Apply k-means Clustering

Clustering is a powerful technique for grouping similar data points. We’ll use the k-means algorithm. Step 1: Create a Sample Dataset Step 2: Apply k-means Clustering

We can create faceted plots and combine multiple visualizations. Faceted Plot Combining Plots You can also use the patchwork package to combine multiple plots:

Let’s analyze a simple time series dataset using the forecast package. Step 1: Install and Load Forecast If you don’t have forecast installed, you can install it: Then, load the library: Step 2: Create a Time Series Dataset We’ll create a sample time series dataset: Step 3: Decompose the Time Series Step 4: Forecasting

We’ll demonstrate a basic machine learning workflow using the caret package for building a predictive model. Step 1: Install and Load Caret If you don’t have caret installed, you can do so with: Then, load the library: Step 2: Create a Sample Dataset We’ll use the same dataset but add a binary outcome variable to…

We can perform a t-test to compare the means of weight between two age groups. Step 1: Create Age Groups Step 2: Conduct a t-test

Let’s create more complex visualizations, such as a boxplot and a density plot. Boxplot Density Plot
